IMPROVEMENT IN POTATO-DIGGERS.

Specification forming part of Letters Patent No. 123,966, dated February :20, 1872.

To all whomtmay concern:

Be it known that we, DANIEL S. WING and HENRY GREEN, of Rome, in the county of Oneida and State of New York, have invented a new and valuable Improvement in Potato-Diggers; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is arepresentation of an under-side plan view of our invention. Fig. 2 is a vertical longitudinal section of the same.

This invention has relation to potato-diggers; and consists inthe constructionIa-nd novel arrangement of devices by means of which the potato-hills are opened, the potatoes separated from the earth, and gathered in hills on the surface in the rear of the separators.

Referring to the accompanying drawing, A represents a rectangular frame, supported by the separating-wheels B B, and provided with I the caster-wheels b b and the guiding-handles b. U designates reversible mold-board plows, secured to the frame A in front of the wheels B B. They are employed for the purpose of removing obstructions during the work of digging potatoes; also, by proper adjustment, as devices for culti\l'ating, gathering' the earth into hills, Src. D represents a plow attached to the central longitudinal beam a of the frame A, and arranged between the wheels B B. Its function is to open the potato-hills and to throw their contents to either side. It has two mold-boards, which are hinged togetherand adjusted'to different-sized hills by means of the regulating-arms c c, one of which is slotted, and connected to the other by a pin or screw-bolt. d d represent the rea-r standards of the plow D, pivoted to the beam a. d1 represents the forward standard, which passes through a longitudinal slot in the beam a, and holds a nut, d2, both above and below the beam c. of the adjust-ment of the plow to different depths and positions. E represents separating-teeth, which project inwardly fom the Itis so arranged in order to allow rims of the wheels B B, and are bent slightly, as shown. Their tendency is to rake and separate the potatoes from the upturned soil, and to deposit them in a row behind the plow D. The teeth Epass through the rims ofthe wheels B B some distance beyond the outer faces thereof, as shown at E1, and are bent inwardly, so as to form a guard to prevent the potatoes from being thrown outside the wheels. For the more eii'ectual accomplishment of this purpose, other teeth, E2, may be attached to the rims of the wheels, as shown in the drawing, their inner ends projecting slightly beyond the inner faces of the wheels B B. The

Wheels B B are j ourn aled to a transverse shaft, B1, and held in position by means of collars B2 on each side of both wheels. By loosening and moving these collars, the positions of the wheels may be changed to lessenv or increase their distance apa-rt. The shaft B1 is supported on the frame A by means of standards A. y

The implement as described may be used in digging pea-nuts.

I claim as my inventionl. In a pea-nut or potato digger, the separating-wheels B B, armed with the inner and outer rows of teeth E E1 and E2, arranged, in relation to each other and to the plow D, as and for the purpose specified.

2. The improved plow D, hinged to the frame A of a potato or pea-nut digger, and rendered vertically, longitudinally, and laterally adjustable, as described.

3. In a potato or pea-nut digger, the combination of the hinged mold-boards, constituting the plow D, the pivoted standard d, vertical standard d1, nuts d2, and slotted beam a, as and for the purpose described.

4. The wheels B, armed with the teeth E, and rendered laterally adjustable on the shaft B1, as described.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
